Engorged breasts. 😩

Jacquelyn
So it's been 3 days since my son was born. My breasts are rock solid, huge and very tender. I'm formula feeding him. I've been told many ways to relieve this pain. I have pads in my bra and I've been putting cabbage leaves in there. I wear sports bras anyway so I have the support. I've also been told to hand express, but I've still got some questions about that. Will hand expressing encourage my body to make more milk thinking I'm feeding? Should I just dispose the breast milk or feed it to him? How long will it take for this to work? Any advice or tips would be helpful! Thank you!
